Question 216 of 481
1Z0-811 Exception Handling and Development Tools Practice Question
Which THREE statements are true about the Java logging API (java.util.logging)?
⚠ Common exam trap
Oracle often tests the misconception that the default logging level is FINEST or that all loggers automatically forward every message to the root logger, but in reality the default level is INFO and forwarding depends on level checks and the useParentHandlers flag.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Handlers can be attached to loggers to output messages
The Java Logging API allows Handlers (such as ConsoleHandler, FileHandler, or custom handlers) to be attached to Logger objects to output log messages to destinations like the console, files, or network sockets. This is a core design pattern of the API: loggers produce log records, and handlers are responsible for publishing them.
